Abstract
The utility model discloses an agricultural seed-metering device anti-reverse device. The agricultural seed-metering device anti-reverse device comprises a travel chain wheel, a seed-metering chain wheel, a rotation shaft and a link chain, wherein the travel chain wheel is connected with the seed-metering chain wheel through the link chain and the seed-metering chain wheel is arranged on the rotation shaft. The anti-reverse device is characterized in that the travel chain wheel is installed on a power output shaft indirectly through a one-way bearing, the inner ring of the one-way bearing is sleeved on the power output shaft; the travel chain wheel is sleeved on the outer ring of the one-way bearing in a tight fit manner; and the seed-metering chain wheel is directly sleeved on the rotation shaft, and a key is used to form the keying fit fixed joint. The one-way bearing is added on the travel chain wheel of the agricultural seed-metering device anti-reverse device to reverse the seed-metering device so as to replace the operation that a tractor driver operates a clutch fork assembly during reversing, thus influences on the seed-metering of the seed-metering device caused by the personal factor can be reduced; and parts such as the operation clutch fork assembly and the bearing in the chain wheel semi-clutch are reduced, thus the operation is easier and the structure is simpler.
Description
Technical field
The utility model relates to a kind of agricultural machinery seeding unit parts, relates to the anti-reverse mechanism of no-tillage and direct-seeding machine seeding units such as a kind of suitable agriculture rape seed specifically.
Background technology
At present; The general device that prevents the seeding unit counter-rotating that uses of agricultural machinery producer; As depicted in figs. 1 and 2ly give the half-clutch device 205 of sprocket wheel by walking sprocket wheel 208 transferring power, under the elastic force effect of spring 201, rabbet and touch by the tooth of the tooth embedding of half-clutch device 202 and sprocket wheel half-clutch 205 when operate as normal for half-clutch device 202; Half-clutch device 202 sows for rape seed seeding unit 206 through key 203 transferring power; Then will the tooth embedding of half-clutch device 202 and the tooth embedding of sprocket wheel half-clutch 205 separated through clutch fork assembly 210 during the tractor reversing, rotating shaft 204 is not turned round, rape seed seeding unit 206 not be sowed.This matching requirements tractor driver must pull out clutch fork assembly 210 earlier before reversing separate the tooth embedding of half-clutch device 202 and the tooth embedding of the half-clutch device 205 of sprocket wheel; Rotating shaft 204 is not turned round; Thereby realization rape seed seeding unit 206 is not sowed; Yet find in the actual production to forget controlled clutch fork assembly 210 when some tractor driver moves backward that the counter-rotating of rape seed seeding unit is damaged rape seed by pressure and stopped up the feed outlet on the seeding unit during reversing, influences the stability of seeding unit seeding.
Therefore; Must further improve the anti-reverse mechanism of no-tillage and direct-seeding machine seeding units such as agriculture rape seed; Rape seed seeding unit counter-rotating is damaged rape seed by pressure and is stopped up the feed outlet on the seeding unit when avoiding moveing backward; Influence the stability of seeding unit seeding, realize that simultaneously tractor driver's more convenient operation and apparatus structure are simpler.
The utility model content
The purpose of the utility model; It is exactly the above-mentioned deficiency that exists to existing agriculture seeding unit anti-reverse mechanism; It is simpler to propose a kind of structure; The device of more convenient operation, this device be a kind of can avoid moveing backward the time counter-rotating of rape seed seeding unit damage rape seed and stop up by pressure the feed outlet on the seeding unit, improve the agriculture seeding unit anti-reverse mechanism of the stability of seeding unit seeding.
The utility model is to solve the problems of the technologies described above the technical scheme that is adopted: a kind of agriculture seeding unit anti-reverse mechanism; Comprise walking sprocket wheel, seeding sprocket wheel, rotating shaft, chain, wherein, the walking sprocket wheel is connected with the seeding sprocket wheel through chain; Realize the transmission of power, the seeding sprocket wheel is installed in the rotating shaft; Described walking sprocket wheel is installed on the power take-off through unilateral bearing indirectly, and the inner ring of unilateral bearing is enclosed within on the power take-off; Walking sprocket wheel tight fit is enclosed within on the outer ring of unilateral bearing; Described seeding sprocket wheel directly is enclosed within the rotating shaft, and forms the connection of key matching and fixing through key.
As the further improvement of the utility model, unilateral bearing axially through one have a stop screw the back-up ring axial restraint.
As the further improvement of the utility model, said seeding chain wheel side is provided with the back-up ring axial restraint.
During operation; The transmission of power of seeding unit is to realize through the unilateral bearing that power shaft acts on the walking sprocket wheel; Unilateral bearing drives the commentaries on classics of moving in turn of walking chain during operate as normal; The walking sprocket wheel drives the commentaries on classics of moving in turn of seeding chain through chain, and the seeding sprocket wheel acts on seeding unit through rotating shaft and makes the seeding unit seeding; When reversing the time utilizes unilateral bearing idle running, the unpowered output of walking sprocket wheel, seeding unit does not turn round, and anti-running is damaged seed by pressure and is stopped up feed outlet when avoiding moveing backward, and influences the stability of seeding unit seeding.The advantage of this utility model: this agriculture seeding unit anti-reverse mechanism is utilized in walking and adds to adorn unilateral bearing on the sprocket wheel and substitute reversing manual operating on opportunity clutch fork assembly and make that seeding unit is counter to turn round; Having reduced artificial reason is affected the seeding unit seeding; Machine has reduced controlled clutch fork assembly simultaneously; Parts such as bearing in the half-clutch device of sprocket wheel make manipulation and structure simpler.
